. SHUTTLE-MOTION non Looms.

Specification of Letters Patent.

Patented Feb. 2, 1909.

Application filed October 13,1906. Serial No. 338,741.

To all whom it may concern:

Be it knownthat I, Erna H. RYON, a citizen of the United States, residing at Worcester, in the county of Worcester and State of Massachusetts, have invented cer tain new and useful improvements inShuttie-Motions for Looms, of which the following is a specification.

My invention relates to looms, and particularly to that class of looms termed fancy looms, in which drop or change shuttle boxes are used at each end of the lay, and my invention particularly relates to a picking motion for loomsof the class referred to.

In looms of the classreferred to,'the picking motion is. ordinarily operated at every revolution of the crank shaft, on both sides of the loomat the same time. In my improvements the picking motion is operated at every revolution of the crank shaft on the loom, and by this construction the smash of the shuttles is prevented, and less power is required to operate the loom.

My invention consists in, certain novel features of construction ofmy improvements as will be hereinafter fully described.

I have only shown in the drawing a detached part of a loom, and of the picking motion embodying my cient to enable those skillediin the art to understand the construction and operation thereof. V

Referring to the drawing :F igure 1 shows a detached part of a loom with my improvements applied thereto. Fig. 2 is a side view of a picking lever, on line 2, 2, Fig. 1, looking in the direction of arrow. a, same figure. Fig. 3 is asection, on line 3, 3, Fig. 2, looking in the direction of arrow Z2, same figure.

In the accompanying drawing, 1 is a detached portion of the loom sides or end frames, 2 is the crank shaft, 3 are the transverse picking shafts, mounted in suitable bearings in stands l to have a rocking motion, and each carrying a picking shoe ,5, and a picking arm 6, which is connected, through a link or connector 7, with the picker stick,

not shown, in the usual way.

All of the above mentioned parts may be of the usual and well known construction.

Each of the two picking levers 8, one at improvements, sufiieach end of theloom, is pivotally mounted in this instance on studs 9, extending out from opposite sides of a collar 10 which is fast on a rotary shaf't'll, mounted in suitable'bean' ings and has a rocking motion on said studs in the direction of the length of said rotary shaft 11. Each picking lever 8 has in this instance two oppositely extending arms, and carries two rolls 12, mounted upon opposite ends of the picking lever. The rolls 12 are adapted tobe moved into and out of the path of the picking shoe 5 on the picking shaft 3, as the shaft 11 revolves and the picking levers 8 revolve with said shaft.

Splined onthe shaft ll is a collar or sleeve 13, having an annular groove 13 therein, to receive the fork or yoke shaped end of a leverl l, pivotally mounted on a stud 15 carried in a stand or support 16. The upper end of the lever 1 1- is connected, through a link 17, with one arm of a bell crank lever 18, pivotally mounted on a stud 19 in a stand 20, secured to the frame 1.

The other arm of the bell crank lever 18 is connected by a spring give-way rod 21,

through a link 22, with one end of a bell crank lever 23, pivotally mounted on a stud 24,011 a stand 1 on the end frame 1; the other end of the angle lever 23 is connected with an indicating mechanism of the loom.

On the collar or sleeve 13 are two oppositely extending lugs or cars 13, each of which is connected, through an adjustable link 25, with a lug or car 8 on the picking levers 8. The operation of my improvements will be readily'understood by those skilled in the m; The movement of the angle lever 23, by the indicating mechanism, not shown,

through connections to the lever 14:, will slide the sleeve 13 on the shaft 11, shaft revolves, and will, through connections to the picking levers 8, move one lever out as said of the path .of the picking shoe 5 on the "picking shaft 3, and the other lever into the path of the picking shoe5, on the other picking shaft 3, by rocking said picking levers 8 on'their pivotal supports.

It will be understood that the details of construction of my improvements may be varied if desired. In some class of looms, picking levers, pivotally mounted, may be employed with only one arm, to be moved operative position.

2. In a picking motion of a loom, the combinationwith a driven shaft, the picking shafts, and picking shoes, of two picking levers or arms, one for each picking shaft, and each picking lever or arm pivotally mounted on said driven shaft and adapted to have a rocking motion in the direction of the length of said shaft, and connections to said picking levers or arms, to simultaneousl move one out of and the other into operative position, to operate a picking shoe and picking shaft.

3. In a picking motion of loom, the combination with a driven shaft, the picking shafts, and picking shoes, of two picking levers or arms, one for each picking shaft, and each picking lever or arm pivotally mounted on said driven shaft, and adapted to have a rocking motion in the direction of the length of said shaft, and means to simultaneously move one of said picking levers or arms out of and the other into operative position, to operate a picking shoe and picking shaft.

at. In a picking motion of a loom, the combination with a driven shaft, of a picking lever pivctally mounted on said shaft and adapted to have a rocking motion in the direction of the length of said shaft.

5. In a picking motion of a loom, the combination with a driven shaft, a picking shaft, and a picking shoe, of a picking lever pivotally mounted on said driven shaft, and

adapted to have a rocking motion in the direction of the length of said shaft.

6. In a picking motion of a loom, the combination with a driven shaft, a picking shaft, and a picking shoe, of a picking lever, pivotally mounted on said driven shaft and adapted to have a rocking motion relative to said shaft, and thereby be moved into and out of the path of the picking shoe.

7. In a picking motion of a loom, the eo1nbination with a driven shaft, a picking shaft, and a picking shoe, of a picking lever, pivotally mounted on said driven shaft, and

adapted to have a rocking motion relative to said' shaft, and thereby be moved into and out of the path of the picking shoe.

8. The combination with a driven shaft, a picking shaft, and a picking shoe, of a collar fast on said shaft, and having studs extending out from opposite sides thereof, a picking lever having a hub pivotally mounted on said studs, and adapted to have a. rocking motion relatively to said studs, a connection from said picking lever to a collar splined on said driven shaft, and said collar, and means for moving said collar to move said picking lever.

9. In a picking motion of a loom, the combination with a driven shaft, two picking shafts, and a picking shoe on each picking shaft, of two collars fast on said driven shaft, and having outwardly extending studs thereon, and a picking lever for each collar, said lever having hubs pivotally mounted on said studs, and having a rocking motion thereon, connections from said levers to a sleeve splined on said driven shaft, and said sleeve, and means to move said sleeve, to simultaneously move one picking lever into the path of one picking shoe, and the other picking lever out of the path of the other picking shoe.
